Ten 100-year predictions that came true

Ten 100-year predictions that came true
11 January 2012Last updated at 00:09 By Tom Geoghegan BBC News Magazine John Watkins predicted Americans would be taller, tanks would exist and C, X and Q would no longer feature in our everyday alphabet In 1900, an American civil engineer called John Elfreth Watkins made a number of predictions about what the world would be like in 2000. How did he do? As is customary at the start of a new year, the media have been full of predictions about what may happen in the months ahead. But a much longer forecast made in 1900 by a relatively unknown engineer has been recirculating in the past few days. In December of that year, at the start of the 20th Century, John Elfreth Watkins wrote a piece published on page eight of an American women's magazine, Ladies' Home Journal, entitled What May Happen in the Next Hundred Years. Watkins was a writer for the Journal's sister magazine, the Saturday Evening Post, based in Indianapolis. It was picked up and caused some excitement on Twitter. 1. 2. 3. 4. 5. 6.

20 tonnes de poissons échoués Un évènement inhabituel est survenu mardi sur le littoral de la Norvège. Des milliers de poissons, des harengs, se sont échoués massivement sur la berge a indiqué l'Institut norvégien de recherches marines. Selon des médias norvégiens, la quantité de poissons échoués est évaluée à près de vingt tonnes. Ils ont été trouvés près d'une petite localité du nord du pays. Selon Ole Kristian Berg de l'Université norvégienne de sciences et de technologie de Trondheim, les échouages de poisson ont déjà été observés, mais jamais à une telle échelle. Phénomène naturel? Selon le spécialiste, ces poissons auraient pu avoir été pourchassés par des prédateurs, tels que des mammifères marins. Selon la municipalité de Nordreisa, une grande partie des poissons échoués ont maintenant été emportés par les nouvelles marées. Un phénomène similaire s'était produit en janvier 2011 en Arkansas.

Is radix sort faster than quicksort for integer arrays? discussion at reddit There are plenty of misconceptions and confusion over radix sort on the internet. The wikipedia article is messy and unclear, and focuses more on trying to explain the philosophy (for lack of a better word) than the characteristics and capabilities of radix sort. American Flag Sort Worst case performance: O(kN) Worst case space complexity: O(k log N) In Engineering radix sort McIlroy et al. discusses how radix sort can be used successfully to sort arrays of strings, using the American Flag Sort variant. The algorithm can be adapted into a high performance sort algorithm for integers, as shown by Birkeland in Searching large data volumes with MISD processing. Implementation The implementation proved to be surprisingly simple. “The troubles with radix sort are inimplementation, not in conception” - McIlroy et al. (1993) The complexity is O(kN) with k = 4 for 32-bit integers. Benchmark sort Hardware: Language options: C++: -O3 -o radix Java: -Xmx10G Arrays.sort

Five Predictions For The Future Of Energy It seems like a new prediction pops up for how we will use renewable energy in the coming decades every day. Will we be using all solar in two years? In five? Prediction: Solar Energy Will Be More Economical Than Fossil Fuels In 10 Years So says the Institute of Electrical and Electronic Engineers (IEEE). Prediction: Solar Power Will Be As Cheap As Coal in Two Years No need to wait a decade--the researchers over at Bloomberg New Energy Finance think that solar power could reach grid parity (the point at which solar is as cheap for utilities as fossil fuels) in the next two years. Prediction: Natural Gas Will Kill Renewables Natural gas produced from shale will kill the economics of renewable energy in the coming years, according to a report from Reuters. Prediction: Renewable Energy Use Will Grow, But So Will Coal And Natural Gas Use The good news: The International Energy Association believes that renewable energy will grow from 8% of total energy use in 2009 to 13% in 2035.

Shark Swallows Another Shark Whole algorithm - In-Place Radix Sort Synthetic biology and the rise of the 'spider-goats' | Science News Cops release 3 boys questioned in Logan Square sex assault Three teenaged boys being questioned for the New Year's Eve attack on an 18-year-old Highland Park woman came to the Logan Square neighborhood to attend a concert were released without charges late Sunday, the Tribune has learned. The young woman was sexually assaulted and beaten into a coma after she came to the city to attend a Saturday night performance at the Congress Theatre by Rusko, an English producer of electronic dance music and DJ whose real name is Christopher Mercer. But rather than going into the show the woman went into a restaurant on Milwaukee Avenue, across the street from the theater, the source said. While inside the restaurant, she met three people with whom she left, the source said. She was found a short time later on a nearby lawn, apparently beaten unconscious during a sexual assault, police said. The three juvenile males were released from police custody at about 10 p.m. The three, described as being in their mid-teens, were taken into custody.

How Speeding The "Most Important Algorithm Of Our Lifetime" Could Change This Modern World Last week at the Association for Computing Machinery's Symposium on Discrete Algorithms (SODA) a new way of calculating Fast Fourier Transforms was presented by a group of MIT researchers. It's possible that under certain situations it may be up to ten times faster than the current way we do these. At this point you are probably wondering: What the hell is he talking about? Let me explain, because improving these three little letters--FFT--may change your life. Here's a quickie explainer: Fourier transforms are a mathematical trick to simplify how you represent a complicated signal--say the waves of sound made by speaking. How so? Now, you should remember that sound waves, and both picture and video signals, are all handled by processors in your TV, PC, and phone, and that the radio waves that whizz through the air to keep us all connected to the Internet need digital processing too. So calculating FFTs up to ten times faster is a big deal. [Image: Flickr user hazure]

10 Amazing Tales of Alien Abduction - (alien abduction, martians...) Are alien life forms visiting Earth and performing experiments upon unwitting human victims? This is one of the world's greatest mysteries! Read on to discover ten of the most famous and astounding cases of alien abduction ever documented. The Allagash Waterway Abduction One of the most famous cases of alien abduction is The Allagash Waterway Abduction, which took place in Maine in 1976. The object began to change colors before their eyes, and one of the men used a flashlight to signal to it. The men returned home, but soon all four were haunted by nightmares in which they remembered being experimented on by aliens in a space craft. All four men received separate hypnosis sessions, but their stories were all exactly the same. Betty Andreasson taken aboard the mother ship On January 25, 1967, homemaker Betty Andreasson and her family were astounded when the electricity in their home suddenly went out and a bright red light shined in through their kitchen window.

Burstsort Burstsort algorithms use a trie to store prefixes of strings, with growable arrays of pointers as end nodes containing sorted, unique, suffixes (referred to as buckets). Some variants copy the string tails into the buckets. As the buckets grow beyond a predetermined threshold, the buckets are "burst", giving the sort its name.
